Questions and Answers about the Coronavirus Vaccine

Mass immunization programs have been launched around the world as part of the Covid-19 epidemic. These can often seem confusing due to the variety of information and instructions available, but there is some basic information about vaccines that can be avoided if known. Here are some of your questions and answers about the coronavirus vaccine.

What is a vaccine?

Vaccines prepare the human body to fight against a specific infection, virus or disease. The vaccine contains an inactive or weakened part of the substance that causes the disease, called a “blueprint.” This part of the body develops a similar response that helps the body’s immune system to detect and fight the virus later on. Vaccines are less likely to make you very ill, but many can have some side effects. E.g., hand pain or mild fever.

However, the next step is to get the immune system against the disease. According to the US Centers for Disease Control and Prevention (CDC), the most powerful thing about a vaccine is that when other drugs cure or cure a disease, the vaccine prevents that disease.

Is the vaccine safe?

An early form of the tick was discovered in China in the 10th century. However, it was not recognized until 1796. That same year, Edward Jenner found that a mild infection with cowpox protected him from smallpox. He experimented with this theory and discovered the smallpox vaccine two years later, and the word vaccine has been derived from the Latin word “Vaka” ever since. The Latin word Vaka means cow.

The most important achievement in the medical world of the modern world is the vaccine. According to the World Health Organization, vaccines prevent at least 20-30 million deaths worldwide each year and protect against more than 20 diseases.

The CDC says that before any vaccines are marketed, they are tested in various ways. They are tested on animals in the lab before being applied to the human body in clinical trials and with the approval of health managers. There are risks but the benefits outweigh the risks.

For example, it is the spring that has killed billions of people. Which has been prevented. However, it takes decades to achieve this kind of success. Only in August last year was Africa declared polio-free. Although vaccination programs around the world began more than 30 years ago. Experts warn that it could take months or even years for people around the world to be vaccinated against Covid-19 and return to normal.

How is the vaccine made?

When the germs of a disease such as bacteria, virus or parasite enter the body, the body’s antigen component increases the production of antibodies to fight against it. Usually, a vaccine injects a dormant or weakened part of an antigen before a germ enters a body during daily life. Then the body’s immune system reacts and resists when the real germ enters the body. Following this new method, a coronavirus vaccine has been developed.

How is the covid vaccine compared?

Pfizer-Bioentech and Modern are two vaccine messenger RNA vaccines that use the virus’s genetic code. Instead of using weak or inactive antigens, these vaccines teach the body’s cells how to make a “spike protein.” This spike protein resides on the surface of the Covid-19 virus. These proteins help to make the antibodies needed to fight the virus.

The Oxford Astrageneca vaccine is different – scientists used to infect chimpanzees by modifying the common cold virus to include some of the genetic code of the Covid-19 virus.

These three vaccines are approved for the United States and the United Kingdom. Pfizer vaccines have been approved in Mexico, Chile and Costa Rica. Brazil, on the other hand, has approved the Oxford and Synovac vaccines.

What are the other covid vaccines?

The CoronaVac vaccine, developed by Beijing-based Synovac, has already been introduced in China, Singapore, Malaysia, Indonesia and the Philippines. This vaccine has been developed using conventional methods such as dead or inactive parts of the virus. However, the effectiveness of this vaccine has been questioned. The question arose after information came from the last round of trials held in Turkey and Indonesia. And researchers in Brazil have already said that the vaccine is only 50.4% effective.

Vaccination has been started in India under the name of Covishield. The vaccine was developed by AstraZeneca and Oxford University. Besides, a local company called Bharat Biotech is producing a vaccine called Kovacin.

Russia is using their own vaccine vector vaccine Sputnik V. Which is made from a version of the virus. This vaccine is also being used in Argentina. The country has already ordered 3 lakh doses of the vaccine.

The African Union has ordered the purchase of about 270 million doses of the vaccine from Pfizer, AstraZeneca and Johnson & Johnson of the Serum Institute of India. However, the vaccine of Johnson & Johnson Company is still in the trial stage.

However, the African Union is expected to receive another 600 million doses of vaccine under the Global Covax program. The COVAX program is run under the joint auspices of the World Health Organization and a vaccine alliance called Cow to ensure immunization for low-income countries.

Should you get vaccinated?

Vaccination has not yet been made compulsory anywhere in the world. However, if there is no health problem, everyone is encouraged to take this vaccine. The CDC says the vaccine protects against Covid-19. It also helps keep others safe. This vaccine is also mentioned as an important tool in overcoming the epidemic.

The World Health Organization says 65% to 70% of people need to be vaccinated to prevent the spread of infection. That means people are being encouraged to get vaccinated. Many people, however, have questioned the speed with which the covid vaccine has been invented. While it is true that scientists spend years designing and testing a vaccine, the global interest in finding a solution has accelerated the production of vaccines. And to do this, the World Health Organization has coordinated the work of scientists, business organizations and health organizations. In short, the immunization program will prevent the spread of covid among billions of people and pave the way for the attainment of hard immunity. The sooner we can achieve this, the sooner we can return to normal life.

How many vaccines for coronavirus have been discovered?

More than 200 companies are in the race to make vaccines globally. According to the World Health Organization, their list includes 154 vaccines in pre-clinical trials. In addition, there are 21 vaccines in the trial with small-scale safety in Face-One. Face Two has 12 vaccines in a safety trial and Face Three has 11 more vaccines in a detailed trial and effectiveness trial. Russia’s Sputnik V is one of the more ticker trials still going on. It is said to work similar to the Oxford vaccine and has been reported to be 92% protected so far.

A vaccine called Janssen’s is being tested on 6,000 people in the UK. More than 30,000 volunteers from around the world have taken part in this ticker trial. China’s Sinopharm and Wuhan Institute of Biological Products are in the final trials. Russia’s Gamelia Research Institute is also conducting a vaccine trial.

Which countries are being vaccinated?

More than one million people have been vaccinated in Israel since the coronavirus vaccination began. This is the highest rate of vaccination in the world. 11.55 out of every 100 people in Israel have been vaccinated. Then there is Bahrain. In that country the rate is 3.49. Britain in third place, rate 1.47. As of December 30, only 138 people had been vaccinated in France. The U.S. target was to vaccinate 20 million people by 2020, but as of December 30, they had vaccinated about 2.8 million people.

Which vaccine is being given in India?

Covishield vaccine for Oxford-AstraZeneca coronavirus produced at the Serum Institute of India will be given. The Serum Institute is an associate of AstraZeneca in the production of this vaccine. They are producing this vaccine in India. Serum Institute – the world’s largest vaccine manufacturer and they are making 50 million vaccines every month. The Oxford-AstraZeneca vaccine, produced in India, is being shipped to Bangladesh, Maldives, Bhutan, Nepal, Myanmar and Seychelles. Which of these shipments is going as a gift, and which is under a commercial agreement with the Serum Institute. Besides, India is sending Covishield to Sri Lanka, Afghanistan and Mauritius. The vaccine will be sent to Brazil under a trade agreement.

How effective is Covishield?

When covishield is given, the human immune system begins to produce antibodies and learns to attack any type of coronavirus that enters the body. The second dose is given after 4 to 12 weeks, and it can be stored at a temperature of 2°C. As a result, it is more easily distributed than the Pfizer-Bioentech ticker. International clinical trials have shown that the Oxford-AstraZeneca vaccine has an efficacy of up to 90 percent when given first half dose and then full dose. However, there are not enough clear data to give the vaccine in this method. The Serum Institute says Covishield is highly effective and has found support in third-degree trials in Brazil and the United Kingdom.

Are there any side effects?

So far, the Covid-19 vaccine is a safe vaccine. However, after taking the vaccine, some people may experience various physical problems. Such as swelling at the site of vaccination, slight fever, nausea, headache and body aches. There is talk of some side effects in the case of Pfizer, Oxford and Modern ticks. One in 10 people are said to have these side effects. These are pain, swelling or redness at the injection site, muscle or joint pain, fever, chills, headache and fatigue.

However, these are considered to be a way for the vaccine to adapt to the body. Side effects have been reported in some of the vaccinated areas around the world so far. About four-and-a-half hundred people are expected to experience side effects by January 18 after the start of the vaccination program in India. One death was reported within 24 hours of vaccination. However, Indian authorities have confirmed that the vaccine had nothing to do with the death.

What is important to know before vaccination?

Vaccines approved in the UK and the US are asking for some information about vaccines. For example, if you have any problems, you need to be careful before getting vaccinated. Before getting vaccinated, you need to tell your doctor if you have any health problems or if you are being treated for any disease. For example, you need to know if you have had a severe allergy to a vaccine before, illness with a high fever, low immunity, cancer treatment, bleeding or injury problems, serious illness, whether you are pregnant or breastfeeding. Also, try to find out if the vaccines you are going to take have any common side effects.

How many doses of vaccine should be taken?

In the case of Pfizer and Bioentech vaccines, two doses of vaccine are needed to protect the body. In the case of Pfizer vaccine, there is a 21-day break between the two doses. The CDC says it is better to take a 28-day break in the case of Modern. However, no information is known about the maximum duration of the break. Experts say the second dose of the vaccine should be taken within the prescribed three weeks or one month. The second dose should be taken four to 12 weeks after the first dose of the Oxford-AstraZeneca vaccine.

How long does it take to start vaccination work?

After vaccination, it takes a long time for the human body to recognize the genetic components of coronavirus and make antibodies and T-cells. These then begin to prevent the virus from invading the body’s cells or to kill the infected cells. “It takes at least two weeks or more for the vaccine to become fully effective,” said Danny Altman, an immunologist at Imperial College London.

Can Covid be vaccinated while taking any other vaccine?

The United States Agency for International Development (USAID) says that if you have been vaccinated with Covid-19, you must wait at least 14 days before taking any other vaccine. Then the vaccine must be taken. Similarly, if you have any other vaccines, you will have to wait 14 days to start getting the Covid vaccine.

Can vaccinated people spread the virus?

That is an important question. But the reality is that no one is sure, says the BBC’s science correspondent David Schukman. This is because two things have been observed in ticker trials. One is whether the vaccine is safe, and the other is how much it can prevent coronavirus sufferers from becoming seriously ill. Good results have been obtained in both cases. But whether the vaccine can spread the coronavirus from one person to another has not been investigated. As a result, it is unknown whether those who have been vaccinated can spread the virus to others.

Is there a risk of getting vaccinated due to vaccination?

The US Centers for Disease Control and Prevention (CDC) says no one will be vaccinated against covidosis. Because none of the vaccines that have been approved so far have a live virus. From which there is a possibility of covid. The vaccines that are being used teach the human body to detect coronavirus and develop immunity against it. There may be temporary fever-like symptoms as part of this process. However, this means that the body has begun to build protection against the virus that causes Covid-19. However, since this protection takes a few weeks to develop, anyone can be infected with covid immediately after vaccination. This means that the vaccine did not have enough time to create protection.

Do victims need to be vaccinated?

The US Centers for Disease Control and Prevention (CDC) says the vaccine should be administered even after covid has recovered. The agency says that because covid has serious health risks and a second risk of being infected, people should be vaccinated whether they are infected or not. However, the incidence of a second attack is very low. And there are even fewer instances of being infected within 90 days after recovering. However, once infected with covid, one should wait 90 days for vaccination. You must take the advice of a doctor in this regard. It is unknown at this time what he will do after leaving the post. And the immune system that is naturally formed due to covid infection varies from person to person.

Can pregnant women get vaccinated?

The US Centers for Disease Control and Prevention (CDC) says pregnant women should be vaccinated if they are at the forefront of the fight against covid, such as doctors or health workers. However, in this case, you must take the advice of a doctor.

Who can’t get vaccinated?

The US Centers for Disease Control (CDC) has issued several guidelines for vaccinating against the coronavirus. The agency says special care should be taken when vaccinating people who have had major allergies or side effects in the past. In particular, they must consult a doctor or undergo some tests before getting vaccinated. However, those who are allergic to food or the environment or oral medications, have no problem getting vaccinated. According to the Bangladesh Department of Health, even those under the age of 18 cannot get vaccinated.

What to do after vaccination?

There may be some side effects after the vaccine and they may last for a day or two. Here’s what to do:

  • Wait 30 minutes at the vaccination center after receiving the vaccine.
  • In case of any physical problem after taking the vaccine, contact the designated health center / health worker / doctor immediately.
  • Live a normal life following the hygiene rules even after getting the vaccine.

Will the vaccine get rid of the infection?

However, experts say the vaccine does not guarantee coronavirus infection. A former program manager at the Department of Health’s expanded immunization program, says no one is sure how long the vaccine will last in the human body. “No one is sure whether the vaccine will last for three months, six months or a year. Because it is unknown. Whether or not to take a booster dose after that is also unknown. So even if people get vaccinated, they have to be careful for a while. ” According to the Child Health Research Foundation, it takes several years before any vaccine is introduced, including its effectiveness. This is an unprecedented situation. As a result, there are questions about many things. However, he also said that although it is unknown how long the protection will last, the companies have found out that the protection will be available.

Doubts about the vaccine

Vaccines have saved millions of lives in the last 100 years. But many countries are reluctant to vaccinate, and the trend is growing.
